"A number multiplies or makes more (times) another number, if the other - as often as the first number is included in it (i.e. the other number), is taken and brought together."

A New Model of Multiplication via Euclid

ABOUT In 1968 at age 7 in Grade 2, Jonathan J. Crabtree noticed Euclid's definition of multiplication made no sense. Two added to itself three times is 8, not 6, as people have said for centuries. (HINT 2 added to itself once is 4.)

Jonathan went on to explore hundreds of original source mathematics books & manuscripts spanning 16 languages. Euclid's definition of multiplication had been incorrectly translated into English in 1570 and was NEVER corrected!

Jonathan's recent published paper and conference presentation titled, The Lost Logic of Elementary Mathematics reveals when why and how western mathematics education came to be filled with mis-truths, contradictions and inconsistencies.
